@joe I think that the upgrade the problem is, too.
I did the upgrade two times.
One time with the software on the Pc but I reinstall 15.04 again because of te many bugs (6 weeks ago)
Then I get the upgrade again via the air.
Next week I will wipe my device and inform you.
Thanks!

Hallo,

I have the same problem with my battery at my Oneplus One as a lot of users with other phones.
With WIFI and without network there is no problem.

NOT using my phone it is empty within about 10 hours

HELP!

I bought a OPO and installed UT yesterday with snap on Ubuntu 16.04. after I have UPDATED the system!
I selected the device manually.
I had to disconnect the OPO from the PC to get it into the recovery mode and than connected it again.
Than the installation began automatically.
Just sitting down and waiting for a while (about 10 minutes).

Everything is working perfect

So it is worth to buy a OnePlusOne !!!
